Abstract
A starter for cranking an internal combustion engine is composed of an electric motor, an output shaft driven by the motor, a pinion gear coupled to the output shaft, and a magnetic switch. Electric power is supplied to the motor from an on-board battery through a switch, a movable contact of which is driven by the magnetic switch. The movable contact is connected to a brush lead wire via a connection formed by soft-soldering. The connection formed by the soft-soldering is positioned close to the commutator and covered with an end cover, so that the temperature of the connection becomes higher than other places in the starter. The connection easily melts away to thereby shut off power supply to the motor when its temperature becomes unusually high, and thereby the starter is protected from overheating.
